A long wait
Of course, for those who feel I am absolutely mistaken, I am just kidding! The rest who have visited Mumbai know that I am not! Out of the rest, who haven't visited Mumbai yet, are simply blessed. My suggestion, in case you happen to visit this city, taking a perspective of "I am so lucky I don't have to come here again and again" will surely help you put up with what you experience here!
From where I see it, people living in this place are always in some kind of hurry and land up missing out on all those elements that complete actions. Their mornings are bad due to lack of good sleep, afternoons are messed up because they reached work late, evenings are frustrating because they are struck in traffic and nights are screwed up because its just now they reached home and have a long list of to do things before they sleep! There is no plane satisfaction of accomplishing anything or peace of mind! Forget mind, there is no peace even in the surroundings. The decibel levels are so high that it can be sinfully painful at times. Pollution levels, best nothing said about that. Just bare in mind, prevention is better than cure while travelling and take all the precautions.
It just gets you thinking what kind of life is this? I mean, what is so brilliant about this lifestyle that people pour in this city so much? A patent answer to this question is "there's money and opportunities". I say, what is the use of that more money when you can't even spend it on things you love only because you are so very busy earning it? What is the use of those opportunities when you can't even enjoy them on every step because of this inherent hurry in and around you all the time?
I am sure even though not everyone living in Mumbai may accept this, but deep down they do dream of a peaceful life!
